Earlier today, Epic Games released Epic Citadel for Android on both Google Play and the Amazon Appstore. Originally released in 2010 for iPhone and iPad, the glorified tech demo served to showcase the company's Unreal Engine 3 running on smartphones and tablets. It also served as somewhat of an intro for Chair Entertainment's Infinity Blade series."While we've licensed our engine to help developers build and ship many fantastic games for Android, Epic Citadel is our first internally developed product to be released to Android users," said Jay Wilbur, vice president of Epic Games. "It's a free, easy way to check out the high-quality experience Unreal Engine technology delivers on mobile devices."

In Epic Citadel, users explore a medieval castle, wandering through various streets, halls and grounds via touchscreen controls. It's little more than a sight-seeing tour, without missions, combat or enemies of any kind.

"Epic Citadel features beautiful, high-performance graphics that are characteristic of mobile Unreal Engine games. Throughout the app's development for Android, we worked closely with Epic Games to ensure that the visuals can be experienced on NVIDIA Tegra-based devices in all of their glory," remarked Tony Tamasi, SVP Content and Technology, NVIDIA."Intel is very pleased to see Epic's award-winning Unreal Engine 3 technology shipping on Android with full native support for x86," said Mukesh Goel, Director of Ecosystem Enabling, Mobile Communications Group, Intel. "We're especially excited by the tremendous performance being realized in 'Epic Citadel' on the Atom Z2460 platform."

"As the leading supplier of mobile and embedded GPUs for both iOS and Android, Imagination has worked extremely closely with Epic for many years as it has continuously pushed the boundaries of mobile graphics with Unreal Engine technology," Tony King-Smith, VP of Marketing, Imagination Technologies. "We are delighted that our collaboration is extending into the Android space and that Epic is making such excellent use of our PowerVR GPUs and tools as it brings the best of gaming capability to the rapidly growing Android market."

For now, it remains to be seen whether this means Infinity Blade games are on their way to Android. Series' developer Chair Entertainment has yet to make an announcement, but we'll let you know if or when it happens.

On a side note, Epic updated the iOS version to support high-resolution devices.
